حلقه r ، nzi نامیده می شود؛ اگر برای هر a?r ، l(a) یک n-ایده آل از r باشد. در این مقاله، ابتدا برخی ویژگی های اساسی و بسط های پایه از حلقه هایnzi را مطالعه می نماییم. سپس منظم بودن قوی از حلقه های nzi را مطالعه و به نتایج زیر می رسیم : فرض کنید r یک sf- حلقه چپ باشد ، آنگاه r یک حلقه منظم قوی است اگر وتنها اگر r یک حلقه nzi باشد . اگر r یک حلقه mc2 چپ nzi باشد و هر r- مدول چپ منفرد ساده، ...
Experiments were conducted to adapt the cloth Nzi trap to a format suitable for fixed applications in biting fly sampling or control. Catches of tabanids [Tabanus L., Chrysops (Meigen), and Hybomitra Enderlein], and stable flies [Stomoxys calcitrans (L.)] in painted plywood traps were compared with those in standard phthalogen blue cloth traps, and in similarly painted cloth traps. The Manitoba...
Near-Zero-Index Materials Near-zero-index (NZI) materials show great promise for photonic devices by enabling new ways to control light–matter interactions. However, reproducibility and mass production of these have proven difficult. In article number 2200109, Jeremy N. Munday co-workers describe how high-quality NZI can be obtained from commercial sources used in novel fundamental photonics.
Pineapple production in Costa Rica increased nearly 300-fold during the last 30 yr, and >40,000 hectares of land are currently dedicated to this crop. At the end of the pineapple cropping cycle, plants are chopped and residues incorporated into the soil in preparation for replanting. Associated with increased pineapple production has been a large increase in stable fly, Stomoxys calcitrans (L.)...

Five adhesive traps and the Nzi cloth-target trap were compared to determine their trapping efficiency and biases for stable flies, Stomoxys calcitrans (L.) (Diptera: Muscidae). Two configurations of the BiteFree prototype trap, constructed of polyethylene terephthalate, were most efficient for trapping stable flies, whereas the EZ trap was least efficient. The two Alsynite traps, Broce and Ols...
Title: Geometry-invariant Phenomena in Near-zero-index Media. When: Friday, December 15, (2017), 12:00. Place: Department of Theoretical Condensed Matter Physics, Faculty of Science, Module 5, Seminar Room (5th Floor). Speaker: Iñigo Liberal, Department of Electrical and Electronic Engineering, Public University of Navarre, Pamplona, Spain & Department of Electrical and Systems Engineering, Uni...
This study was conducted to determine the efficiency of different tsetse traps in 28 sites across Tanzania. The traps used were biconical, H, NGU, NZI, pyramidal, S3, mobile, and sticky panels. Stationary traps were deployed at a distance of 200 m apart and examined 72 h after deployment. The results showed that 117 (52.2%) out of the 224 traps deployed captured at least one Glossina species. A...
Natural photosynthetic photonic nanostructures can show sophisticated light–matter interactions including enhanced light absorption by slow even for highly pigmented systems. Beyond fundamental biology aspects, these natural are very attractive as blueprints advanced devices. But the soft-matter biomimetic implementations of such is challenging due to low refractive index contrast most organic ...
